BACKGROUND OF THE INVENTION

This invention relates generally to table games within a gaming environment and, more specifically, to bonus award systems for use with interactive gaming display tables.

Casinos and other forms of gaming make up a growing multibillion dollar industry both domestically and abroad. Within such environments, table games are an immensely popular form of gaming and are a substantial source of revenue for gaming operators. Such table games are well known and may include for example, poker, Blackjack, baccarat, craps, roulette, and other traditional games. Moreover such table games may include more recently introduced games such as Pai-gow, Caribbean Stud, Spanish 21, and Let It Ride. In a typical gaming event at a gaming table, a player places a wager on a game, whereupon a winning may be paid to the player depending on the outcome of the game. As is generally known, a wager may involve the use of cash or one or more chips, markers or the like, as well as various forms of gestures or oral claims. The game itself may involve the use of, for example, one or more cards, dice, wheels, balls, tokens or the like, with the rules of the game and any payouts or pay tables being established prior to game play. As is also known, possible winnings may be paid in cash, credit, one or more chips, markers, or prizes, or by other forms of payouts.

Although standard, fully-manual gaming tables have been around for many years, gaming tables having more “intelligent” features are becoming increasingly popular. For example, many gaming tables now include automatic card shufflers, liquid crystal display (LCD) screens, biometric identifiers, automated chip tracking devices, and even cameras adapted to track chips and/or playing cards, among various other items and devices. Such additional items and devices add many desirable functions and features to a gaming table, although there are currently limits as to what may be accomplished. For example, known gaming tables that include such added items and devices currently lack a reward feature for players that qualify for a bonus round. Such gaming tables also currently lack a device for advancing game play in steps through user actions taken on a tabletop device.

DETAILED DESCRIPTION OF THE INVENTION

Exemplary applications of apparatus and methods according to the present invention are described herein. These examples are provided solely to add context and to aid in the understanding of the invention. It will thus be apparent to one skilled in the art that the present invention may be practiced without some or all of these specific details. In other instances, well known process steps have not been described in detail in order to avoid unnecessarily obscuring the present invention. Other applications are possible, such that the following example should not be taken as definitive or limiting either in scope or setting. In the detailed description that follows, references are made to the accompanying drawings, which form a part of the description and in which are shown, by way of illustration, specific embodiments of the present invention. Although these embodiments are described in sufficient detail to enable one skilled in the art to practice the invention, it is understood that these examples are not limiting, such that other embodiments may be used and changes may be made without departing from the spirit and scope of the invention.

Various advantages of the present invention include the introduction of devices for use with an interactive gaming table that is more fully automated, providing added benefits to the gaming operator, and also having various automated and player-friendly items and functionalities. The devices described herein may be used to, for example, award bonus jackpots to one or more players and/or to enable one or more players to step through gaming sequences according to the actions of one or more players using such devices.

FIG. 1 is a schematic diagram of an exemplary interactive gaming display table 100. In the exemplary embodiment, table 100 includes at least one processor 102 that is enclosed within a frame 104. Moreover, in the exemplary embodiment, table 100 uses infrared (IR) light to interact with tabletop devices, such as a device 106, that are positioned on or slightly above a display surface 108, which is set within an upper surface 110 of table 100.

In one embodiment, one or more IR light sources 112 are coupled to, such as fixedly secured to, frame 104. In the exemplary embodiment, IR light source 112 includes a plurality of light emitting diodes (LEDs) and the light produced by IR light sources 112 is directed upward towards an underside of display surface 108. Infrared light from IR light sources 112 passes through a translucent layer 114 of display surface 108 and is reflected from any tabletop devices, such as device 106, positioned on, or near, display surface 108. In the exemplary embodiment, translucent layer 114 is fabricated from a sheet of vellum, or any other suitable translucent material that has light diffusing properties. More specifically, after passing through translucent layer 114, the IR light may exit through display surface 108 without illuminating any tabletop devices 106. Alternatively, the IR light may illuminate one or more tabletop devices 106, that are positioned on display surface 108. Moreover, the IR light may illuminate one or more tabletop devices 106 that are positioned adjacent to, but not touching, display surface 108.

Moreover, in the exemplary embodiment, a digital video camera 116 is coupled to frame 104 below display surface 108. More specifically, video camera 116 is positioned with respect to display surface 108 to facilitate maximizing an amount of IR light reflected from tabletop devices 106 positioned above display surface 108. Video camera 116 includes an IR pass filter 118 that transmits only IR light and prevents ambient visible light from traveling through display surface 108. Because it is desired that video camera 116 produce an output signal representative of only the IR light reflected from tabletop devices 106, a baffle 120 is positioned between IR light source 112 and video camera 116 to substantially prevent IR light that is directly emitted from IR light source 112 from entering video camera 116. As such, IR light reflected from tabletop devices 106 may be reflected back through translucent layer 114, through IR pass filter 118, and into video camera 116. Alternatively, IR light reflected from tabletop devices 106 may be reflected or absorbed by other interior surfaces within table 100 without entering video camera 116.

In the exemplary embodiment, translucent layer 114 substantially diffuses both incident and reflected IR light. As such, tabletop devices 106 positioned above display surface 108, but not in contact with display surface 108, will reflect less IR light back to digital video camera 116 than tabletop devices 106 that are positioned in contact with display surface 108. Video camera 116 senses IR light reflected from tabletop objects 106 within its imaging field and produces a digital signal corresponding to images of the reflected IR light. The digital signal is input to processor 102 to enable a location of each tabletop device 106 to be determined. In addition, the size, orientation, and shape of tabletop device 106 may also be determined. Moreover, and as described in greater detail below, a tabletop device 106 may include an IR light reflective pattern or coded identifier that uniquely identifies that particular tabletop device 106 and/or identifies the tabletop device 106 as being within a particular class or group of related tabletop devices 106. Accordingly, the digital signal produced by video camera 116 may also be used to identify a tabletop device 106.

In one embodiment, processor 102 is integral to table 100. In an alternative embodiment, processor 102 is external to table 100 as part of, for example, a server (not shown). As used herein, the term “processor” may include any programmable system including systems using microcontrollers, reduced instruction set circuits (RISC), application specific integrated circuits (ASICs), logic circuits, and any other circuit or processor capable of executing the functions described herein. The above examples are exemplary only, and are thus not intended to limit in any way the definition and/or meaning of the term “processor”. In the exemplary embodiment, processor 102 executes algorithms for processing the digital signal from digital video camera 116 and executes software applications that use a user interface functionality of table 100 to display graphic images. The graphic images include, for example, but are not limited to only including, pictures and/or a virtual environment that is visible on display surface 108. As such, table 100 also includes a video projector 122 that displays graphic images, a virtual environment, and/or text information on display surface 108. In one embodiment, video projector 122 is a liquid crystal display (LCD). In an alternative embodiment, video projector 122 is a digital light processor (DLP) display. To facilitate preventing IR light emitted by video projector 122 from entering table 100, wherein the IR light may interfere with the IR light reflected from tabletop devices 106, a filter, such as an IR cut filter 124, is positioned in front of a projector lens (not shown) of video projector 122.

Moreover, in one embodiment, table 100 also includes a plurality of mirror assemblies 136. Specifically, in the exemplary embodiment, a first mirror assembly 126 directs projected light from video projector 122 through an opening 128 defined in frame 104 such that the projected light is incident on a second mirror assembly 130. Second mirror assembly 130 reflects the projected light onto translucent layer 114, which is positioned at a focal point of video projector 122. Table 100 also includes at least one alignment device 132, which is sized to facilitate properly aligning first mirror assembly 126. A positioning device 134 adjusts an angle of second mirror assembly 130. Such devices 132 and 134 facilitate ensuring that the image projected onto display surface 108 is properly aligned with respect to display surface 108. Alternative embodiments may include alternate elements that may be used to align first and second mirror assemblies 126 and 130. Moreover, other alternative embodiments may not include mirror assemblies 136 and/or devices 132 and 134 but, rather, directly project light from video projector 122 onto display surface 108.

FIGS. 2-4 are schematic illustrations of an exemplary administrator tool or plunger device 200 that may be used with interactive gaming display table 100 (shown in FIG. 1). Specifically, FIG. 2 is a side view of plunger device 200, FIG. 3 is a bottom view of plunger device 200, and FIG. 4 is a cross-sectional view of plunger device 200. In the exemplary embodiment, plunger device 200 may be used to award a player a bonus round or bonus value. Alternatively, plunger device 200 may be used to enable one or more players to move through a game in steps. In the exemplary embodiment, plunger device 200 includes a cylindrical base 202 that includes a top surface 204 and an opposite bottom surface 206. Moreover, plunger device 200 also includes a plunger 208 having a shaft 210 and a handle 212 coupled to an upper end 214 of shaft 210. In the exemplary embodiment, handle 212 is generally oviform. In an alternative embodiment, handle 212 is formed into a “T” shape. Alternatively, handle 212 may be formed into any shape that enables plunger 208 to function as described herein. In the exemplary embodiment, and as best seen in FIG. 3, base 202 is formed with a channel 216 that extends from top surface 204 through base 202 to bottom surface 206. Channel 216 is sized to receive shaft 210 therein and to enable shaft 210 to slide into and out of base 202 as described herein.

Base 202 also includes a primary identifying mark or indicia 218. Primary identifying mark 218 extends over at least a portion of bottom surface 206. In the exemplary embodiment, primary identifying mark 218 functions as a unique identifier for plunger device 200. In the exemplary embodiment, primary identifying mark 218 is a tag that includes an infrared (IR) dot pattern (not shown) that reflects light from IR light source 112 (shown in FIG. 1) as described above. In an alternative embodiment, primary identifying mark 218 is a tag that includes a barcode that is readable by a scanner (not shown) and/or digital video camera 116 (shown in FIG. 1). In other alternative embodiments, primary identifying mark 218 is an RFID tag or any other suitable tag or device, such as a radial code or matrix code, that enables a unique identification of plunger device 200.

In the exemplary embodiment, shaft 210 includes a secondary identifying mark or indicia 220 that extends over at least a portion of shaft 210. Secondary identifying mark 220 is positioned relative to bottom surface 206 such that secondary identifying mark 220 is visible by, for example, digital video camera 116, when shaft 210 has been inserted into body 202. In one embodiment, secondary identifying mark 220 is an IR dot pattern (not shown) that reflects light from IR light source 112 as described above. In alternative embodiments, secondary identifying mark 220 is a barcode (not shown) that is readable by a scanner (not shown) and/or digital video camera 116, an RFID tag, or any other suitable tag, label, or device, such as a radial code or matrix code, that enables processor 102 to read secondary identifying mark 220 in order to associate secondary identifying mark 220 with an award and/or game move. In the exemplary embodiment, digital video camera 116 reads secondary identifying mark 220 when shaft 210 has been inserted into channel 216, and processor 102 thereafter identifies an action and/or award associated with secondary identifying mark 220. Moreover, in the exemplary embodiment, secondary identifying mark 220 is not permanently associated with a single game move or award. But rather, the game move and/or award may change according to a game being played at table 100. Further, a dealer may change the award associated with secondary identifying mark 220 according to predetermined rules regarding a stage of a game and/or an amount of a wager. In addition, in alternative embodiments, plunger device 200 may include more than one plunger 208, wherein each plunger 208 includes a secondary identifying mark 220. In such an embodiment, each secondary identifying mark 220 may be different, or one or more plungers 208 may include the same secondary identifying mark 220. Further, in alternative embodiments, a game move and/or award may be identified when plunger 208 is pulled upward from channel 216. In such an embodiment, digital video camera 116 is no longer capable of collecting IR light reflected from secondary identifying mark 220, and processor 102 thereafter identifies an award associated with secondary identifying mark 220. Furthermore, alternative embodiments may include one or more plungers 208, wherein each plunger 208 includes more than one secondary identifying mark 220.

During operation, and referring to FIGS. 1-4, a player at interactive gaming display table 100 makes a wager on a game such as, but not limited to, Blackjack, Let It Ride, Pai-gow, roulette, and slots. The game is projected by digital video projector 122 by projecting light through IR cut filter 124. The projected light is reflected by first mirror assembly 126 towards second mirror assembly 130 and is then reflected by second mirror assembly 130 through translucent layer 114 for display on display surface 108. At some point during the game, the player may become eligible for an award. At such time, the dealer may place a reward device, such as plunger device 200, near the player. Prior to collecting the award, infrared light emitted by IR light source 112 and reflected by primary identifying mark 218 is collected by digital video camera 116. Digital video camera 116 generates a signal representative of the reflected IR light and transmits the signal to processor 102. Based on the signal's representation of the IR light reflected by primary identifying mark 218, processor 102 identifies plunger device 200.

The player collects the award by depressing plunger 208 into channel 216. Depressing plunger 208 enables IR light emitted by IR light source 112 to be reflected by secondary identifying mark 220. The reflected light is collected by digital video camera 116, which generates a signal representative of the reflected IR light and transmits the signal to processor 102. Again based on the signal's representation of the IR light reflected by secondary identifying mark 220, processor 102 identifies an award for the player. For example, when the award is a bonus game, processor 102 causes video projector 122 to project a bonus game such that display surface 108 is changed to display a bonus game for the player. As another example, when the award is a number of points or dollars, processor 102 adds the points or dollars to the player's account. Alternatively, player may collect an award by pulling plunger 208 upward from channel 216. In such an embodiment, digital video camera 116 is no longer capable of collecting IR light reflected from secondary identifying mark 220, and processor 102 thereafter identifies an award associated with secondary identifying mark 220.

In an alternative embodiment, plunger device 200 may be used to progress through a game, such as through step-by-step progression of player moves and/or decisions. For example, a player at interactive gaming display table 100 makes a wager on a game such as, but not limited to, Blackjack. As described above, the game is projected by digital video projector 122 by projecting light through IR cut filter 124. The projected light is reflected by first mirror assembly 126 towards second mirror assembly 130, wherein the light is then reflected by second mirror assembly 130 through translucent layer 114 for display on display surface 108. In such an embodiment, the dealer or operator will place a plunger device 200 near the player at the time the wager is made. To identify the player's decisions during play the plunger device 200 is associated with the player according to the primary identifying mark 218. As described above, infrared light emitted by IR light source 112 and reflected by primary identifying mark 218 is collected via digital video camera 116. Digital video camera 116 generates a signal representative of the reflected IR light and transmits the signal to processor 102. Based on the signal's representation of the IR light reflected by primary identifying mark 218, processor 102 identifies plunger device 200 and associates plunger device 200 with a player position at table 100 and determines that the player will be using plunger device 200 to advance through the game.

In the alternative embodiment, and during game play, the player signals each game-related decision by depressing plunger 208 into channel 216. Depressing plunger 208 enables IR light emitted by IR light source 112 to be reflected by secondary identifying mark 220. The reflected light is collected by digital video camera 116, which generates a signal representative of the reflected IR light and transmits the signal to processor 102. Again, based on the signal's representation of the IR light reflected by secondary identifying mark 220, processor 102 identifies an action, such as changing the state of the game, performed by the player. Processor 102 then projects the identified action as described above. For each decision that occurs during game play, the player depresses plunger 208 into channel 216. Processor 102 associates each successive signal representative of IR light reflected from secondary identifying mark 220 as a new decision by the player, and causes the displayed game to change accordingly. Alternatively, a player decision may be identified when plunger 208 is pulled upward from channel 216. In such an embodiment, digital video camera 116 is no longer capable of collecting IR light reflected from secondary identifying mark 220, and processor 102 thereafter identifies player decision associated with secondary identifying mark 220.

FIG. 5 is a schematic illustration of an alternative administrator tool or bonus device 500 that may be used with interactive gaming display table 100 (shown in FIG. 1). Specifically, FIG. 5 is a top view of bonus device 500. In the exemplary embodiment, bonus device 500 includes a base 502 and a door or lid 504. Lid 504 is hingedly coupled to base 502 by one or more hinges 506. Specifically, in the exemplary embodiment, a first hinge portion 508 is coupled to base 502 and a second hinge portion 510 is coupled to lid 504. Hinges 506 enable lid 504 to be swung or lifted from base 502. Lid 504 includes a handle 512. In the exemplary embodiment, handle 512 is substantially centered with respect to lid 504. In one embodiment, handle 512 is formed integrally from lid 504. In an alternative embodiment, handle 512 is coupled to a top surface 514 lid 504 by a mechanical coupling device such as, for example, screws or an adhesive.

Base 502 also includes a primary identifying mark or indicia 516. Primary identifying mark 516 extends over at least a portion of a bottom surface 518 of base 502. In the exemplary embodiment, primary identifying mark 516 functions as a unique identifier for bonus device 500. In the exemplary embodiment, primary identifying mark 516 is a tag that includes an infrared (IR) dot pattern (not shown) that reflects light from IR light source 112 (shown in FIG. 1) as described above. In an alternative embodiment, primary identifying mark 516 is a tag that includes a barcode that is readable by a scanner (not shown) and/or digital video camera 116 (shown in FIG. 1). In other alternative embodiments, primary identifying mark 516 is an RFID tag or any other suitable tag or device, such as a radial code or matrix code, that enables a unique identification of bonus device 500.

In the exemplary embodiment, lid 504 includes a secondary identifying mark or indicia 520. Secondary identifying mark 520 extends over at least a portion of a bottom surface 522 of lid 504. In the exemplary embodiment, secondary identifying mark 520 is positioned in relation to IR light source 112 and digital video camera 116 such that secondary identifying mark 520 is visible to, for example, digital video camera 116 when lid 504 is in a closed position against base 502. In one embodiment, secondary identifying mark 520 is an IR dot pattern (not shown) that reflects light from IR light source 112 as described above. In other embodiments, secondary identifying mark 520 is a barcode readable by a scanner (not shown) and/or digital video camera 116, an RFID tag, or any other suitable tag, label, or device, such as a radial code or matrix code, that enables processor 102 to read secondary identifying mark 520 in order to associate secondary identifying mark 520 with an award and/or game move. In the exemplary embodiment, digital video camera 116 reads secondary identifying mark 520 when lid 504 is in a closed position. When lid 504 is opened, digital video camera 116 is no longer capable of collecting IR light reflected from secondary identifying mark 520, and processor 102 thereafter identifies an award associated with secondary identifying mark 520. Moreover, in the exemplary embodiment, secondary identifying mark 520 is not permanently associated with a single game move or award, but rather, the game move and/or award may change according to a game being played using table 100. Further, a dealer may change the award associated with secondary identifying mark according to predetermined rules regarding a stage of a game and/or an amount of a wager. Alternatively, an award may be identified when lid 504 is lowered to rest against base 502. In such an embodiment, digital video camera 116 recognizes the presence of IR light reflected from secondary identifying mark 520, and processor 102 thereafter identifies an award associated with secondary identifying mark 520. Furthermore, alternative embodiments may include a lid 504 that includes more than one secondary identifying mark 520.

During operation, a player at interactive gaming display table 100 makes a wager on a game such as, but not limited to, Blackjack, Let It Ride, Pai-gow, roulette, and slots. The game is projected by digital video projector 122 by projecting light through IR cut filter 124. The projected light is reflected by first mirror assembly 126 towards second mirror assembly 130, and is then reflected by second mirror assembly 130 through translucent layer 114 for display on display surface 108. At some point during the game, the player may become eligible for an award. At such time, the dealer may place a reward device, such as bonus device 500, near the player. Prior to collecting the award, infrared light emitted by IR light source 112 and reflected by primary identifying mark 516 is collected by digital video camera 116. Digital video camera 116 generates a signal representative of the reflected IR light and transmits the signal to processor 102. Based on the signal's representation of the IR light reflected by primary identifying mark 516, processor 102 identifies bonus device 500. The player collects the award by moving lid 504 upward from base 502. As lid 504 is moved, IR light emitted by IR light source 112 is no longer reflected by secondary identifying mark 520. The loss of reflected light is recognized by processor 102, and processor 102 identifies an award for the player based on secondary identifying mark 520. For example, when the award is a bonus game, processor 102 causes video projector 122 to project a bonus game such that display surface 108 is changed to display a bonus game for the player. As another example, when the award is a number of points or dollars, processor 102 adds the points or dollars to the player's account.

FIG. 6 is a top view of a bonus device 600 that includes a base 602 and a plurality of doors or lids 604. Each lid 604 is hingedly coupled to base 602 by one or more hinges 606. In the exemplary embodiment, a first hinge portion 608 is coupled to base 602 and a second hinge portion 610 is coupled to lid 604. Hinges 606 enable lid 604 to be swung or lifted from base 602. Each lid 604 includes a handle 612. In the exemplary embodiment, each handle 612 is substantially centered with respect to a respective lid 604. In one embodiment, handle 612 is formed integrally from lid 604. In an alternative embodiment, handle 612 is coupled to a top surface 614 lid 604 by a mechanical coupling such as, for example, screws or an adhesive.

Base 602 also includes a primary identifying mark or indicia 616. Primary identifying mark 616 extends over at least a portion of a bottom surface 618 of base 602. In the exemplary embodiment, primary identifying mark 616 functions as a unique identifier for bonus device 600. In one embodiment, primary identifying mark 616 is a tag that includes an infrared (IR) dot pattern (not shown) that reflects light from IR light source 112 (shown in FIG. 1) as described above. In an alternative embodiment, primary identifying mark 616 is a tag that includes a barcode that is readable by a scanner (not shown) and/or digital video camera 116 (shown in FIG. 1). In further alternative embodiments, primary identifying mark 616 is an RFID tag or any other suitable tag or device, such as a radial code or matrix code, that enables a unique identification of bonus device 600.

In the exemplary embodiment, each lid 604 includes a secondary identifying mark or indicia 620.
